You asked me for advice, and so I shall give. However, I might be a little harsh, just as an advance warning. The first thing I'd recommend is to either buy a better camera (if your current one is bad, which is very unlikely) or invest in a tripod, because the #1 cause of blurry pics is unsteady hands. Take the time to focus and remove the shaking and you'll get much crisper and more detailed pictures even with a low-quality camera. As for the build itself-- I'm actually rather impressed with the overall form. I like the ideas used in the railguns, and reverse-jointed legs have always been a favorite for me. However, some of the detail (like the fins in the back) seems almost slapped on as an afterthought. Also, the colors are a little varied-- as a general rule, I try not to mix dark and light gray with dark and light blay, and also to avoid the use of chrome or metallic parts simply because they don't fit well in most MOCs. Here are some more tips I've given others asking for my advice:
Quoting Toby Heinemann
#1-Color Coordination-- you don't necessarily have to only use one or two colors, but adding more often detracts from the look of an MOC. Know why military camouflage works? By using a variety of colors with an unusual and asymmetric pattern, military camouflage breaks up the outline of an object by changing the way the brain perceives it. However, using any strong color in moderation (such as lime green or orange) or as an accent can have amazing results. A link that might help:
http://www.colormatters.com/colortheory.html#2-Photography-- Much less of a necessity than good color coordination, photography is nonetheless important: Even if you've made the best MOC ever, if nobody can tell what it is they won't care. I'm not saying anyone's photography is bad, but it can always get better. For better pictures, there are three important tips: a) Have a solid background (usually black or white are best, for this go to a store and buy a few feet of color cotton, should be well under 5$) b) Have a good light source (a desk lamp is good, a fluorescent light bulb better, outside can be good or bad) c) Use a tripod. The stability, and thereby clarity, difference is amazing. #3-SNOT-- An acronym for Studs Not On Top. This is getting into the more advanced disciplines of building, and is mostly experimentation. Look very closely at other MOCer's work, and see if they use any unusual brick techniques. Fiddle around with your parts, maybe removing part of a two-piece component (like a steering wheel or turntable) and seeing if it combines with other pieces. The best sites I've seen for this are:

http://www.brothers-brick.com/ #4-Greebling-- This is the codeword for 'detailing' among the MOCpages community. Much like SNOT, a large part of it is experimentation. In general, any piece that you never think you would use you can use to greeble, and use lots of tiny parts. Often greebling is tied into SNOT, as the techniques to greeble are similar and sometimes identical to those for SNOT. For this, many of the large SHIPS on MOCpages are great examples-- they have TONS of greebles. Some good sources:
http://www.mocpages.com/moc.php/46658 http://www.mocpages.com/moc.php/1086#5-Inspiration-- This is the only place I can't give a specific reference. Basically, find something, somewhere that motivates you to build something, and then build it! As an example, I'm into mecha, spacecraft and tanks, so I do research on those in my free time. Google is great for images.
Hopefully these tips will help.
