Tygrin's Sprites [WIP]

[Vipershark]

I took a stab at your mushroom.
I changed all but one of your red shades and added some slight hue shifting which I think makes it look a bit more vibrant as well as gave the outline on the lower white part a lot more contrast.

If you don't mind, could you not save your sprites with transparent backgrounds, please?
Paint doesn't play well with transparent (or 0,0,0 black or 255,255,255 white) backgrounds and can be really annoying when editing sprites.
Instead I recommend using a nice desaturated hue which appears nowhere else in your sprite so that it's easy on the eyes.

I'd also ask you to use an image host instead of attachments but I'm not allowed to ask people to do that anymore... >.>
