It looks like it's popping out at you. That is an awesome dragon. And it does remind me of those games I used to play in the good ol' days. This dragon is really cool, the colours are wel chosen. I think it's great, whether you were only limited to sixteen colors or not.
Simplicity can be a virtue in art.
Also, you've proven that nostalga can be spread. I also like the blue you used for shading. Oh well, such is life. Again, great work. Tuija My friend draws dragons and this dragon is nice even the colors are dark.
