So I recently started working on some PNGs, now, I am by no means a graphic artist, (I don't consider myself on the level of the graphic artists here in EAW) but I started working on PNGs after learning how to make them through my mobile device through an app. 
Though since I can't seem to figure out how to post these PNGs without the rendering being screwed over by coding, I had to post them on Imgur as opposed to uploading them straight from my computer.

PNG #2 (Adam Blampied)

Since I am the type to thrive off of criticism, feel free to tell me how I did. Either way though, thank you for viewing them.

it's pretty decent for the first timer. just a bit of smoothing around. I think it's okay to get rid of the white outline around the hair. but so far it's good!

Adam's hair could use a bit of smoothing out around the edges. Overall pretty awesome
