Metal Slug-styled Metal Gear?

[SleepyHarry]

The sprite has good shape, but its not big enough. REX was [huge]. And as said above, the shading is not even close to Metal Slug.

Good start, but it needs some tweeking.

Thanks; i was aware that it was it isn't huge enough, but if it was any bigger, it wouldn't actually fit on the (neogeo) screen. Also, for the shading; any suggestions on what need fixing up?
