When he mentions it, it actually reminds me slightly of one of them ponies.
Anyways, why not try some other colors? You've been using lots of pink and green/blue recently, and the hair is shaded and almost shaped the same as in your last texture, try being original! The horns have already been done a thousand times, even by me once.
Look for inspiration, create something no one has made before! ^^
A humanoid being with a large mouth and drool, a beat up nerd with broken glasses and band-aids etc. Brainstorm a little, write down every word that comes to mind and pick the ones you like the most, even if they are silly!
poop, potato, spaghetti, snow,
cocaine,
white, hamster, hair, fur, tickles,
nose, fingers, nails, snot... Etc.
Marked words make me think of a man with a big nose and some white dust beneath it, could be a cool head.
Try using complimentary colors, triad, monochrome etc.

if you don't have a color library like I do in Illustrator, this is a helpful tool.
I like your style, keep it up and you'll come up with something magical ^^
