Eleventy billion /10. Freaking awesome, the only thing that irks me is that the fire below one could be slightly cropped on the left.
Damn those are really good. I like the secnd one the most. Definite 10/10 Update this if you get more done. I think most of us would love to see them.
Yep, I love the third one as well. Not really into those sorts of games but that siggy is very cool. The metroid one seems very dark on the left and I cannot really see if there is anything going on there. The fonts that you have used seem cool and they go very well with the siggys you have made.
