First of all, sorry for the amount of threads and projects I never finished. (Largely loss of attention. I blame it on a syndrome I have but regardless.)
Right now I'm working on a mech that's greatly inspired by the Metal Slug series (Can't wait to play it.), directly down to using a sprite's pallete (I'm sorry.) for it. I got nice results, however, I want your opinion what else I could do with it or what I should fix on, I originally intended it to be a sort of walker mech, but I never got the legs to look right so I made it into a sort of floater mech. However, the cockpit is largely not how I imagined it but it should do atleast.

If all goes to worst, I might have to redesign it. Which troubles me, making detail on the metal is rather difficult, so it won't look plain. (Which is one part I hate.)

Sorry, too many colors for one section now. Contrast as in making the individual shades (As far as I would understand by his request) more visible to distinguish without zooming.

I think, just my general opinion, is that it starts as normal, 3d road, than a depth-less 2d section, and an equally depth-lessbackground.

Yeah, it looks a bit like tentacles rising out and whacking something. Maybe try to follow the build of your previous 'vertihoriz' () waves attempt, since this attempt looks a bit empty and how the waves rise.

Actually, given some thought, his spine does make sense. The blue line however depicts it somewhat wrong. It would look awkward however, since the part of the tail on the right seems to be lower. It should be a bit higher, otherwise.. It's fine.
