This is a great entry. Besides the fact that the game was pretty cool and this one brings back these memories, it is also very well drawn.
First off I like your colouring and shading. Not only the technique but also the colour choice.
Secondly it's impressive how clean and smooth everything looks. Especially considering that it is hand drawn with several different tools. I would have smudged everything all over the pic I guess. :P
Finally I like how you coped with all the different light sources. I may not be an expert, but it seems you've managed them all well.
Overall a great piece!
5/5 & 10/10
