This is a lot tidier than most custom clones; you've got a lot of skill. I would suggest improving your presentation, like make a more interesting background, maybe some rubble and a white sheet would go a long way.
As requested, here is my opinion on this. ;) Well, obviously you need to improve your photography skills as the pictures are just too blurred (due to wrong focus). Try to take a photo with some distance but use the zoom function to make Wolffe fill out the whole picture. It'll bring better results. ;) Other than that, depending on the reference picture used, this is quite well done. I know how hard it can be to paint stuff by hand as I am into 1:72 scale and 1:30 scale models a bit. ^^
Very cool custom work. I would suggest to find a set of fine tip markers, scotch tape and crazy gule with the brush. I also do custom work on my minifigs like the minifigs in white playing pool on my last creation. I first paint them or draw the suit outline then buttons and tie. But so it won't fade when I'm done, I stretch a piece of scoth tape over the collored piece, then brush the edge of the placed tape with crazy glue to seal the tape onto the body, and to make sure the tape doesn't peel off. I hope to see more creations from you soon.
