Sweeeeet! =)

very realistic, the toes and leg joints look they might actually work on a real one. (there are walker episode 3 troops in minifgure form(also called arc troopers))

I'm liking the feet design!

Very nicely done! My favorite is the leg/feet design. My suggestions would be to add lime green plates to the front panels and to add 2x2 radar dishes to the "joints" of the legs.

Well, it looks long because of the side plates, but that's the smallest kind of that piece there is, so I added it anyways... I'll see if I can improve it with something else, though. The rest of the front in the middle is accurate, though. This was one of my reference pics: http://starwars.wikia.com/wiki/File:AT-RT.jpg As you can see, the laser cannon and the mortar launcher should be there, but the side plates should be one stud shorter. The "real" AT-RT's laser cannon is placed on the front, where the side plates end.

Make the front a little shorter. :p

So, any suggestions as for what I should improve for the next version? (I shortened the laser cannon now, looking for something new for the front's side plates.)

Nice AT-RT, i love the head design, but i think the green on the top of the head looks too flat and the front gun is slightly too long.

Good, but more work can be done with the front. Besides that it's good...

good job its pretty good cant wait to see what other mocs your making.
