Oh dear,  that's lovely little, medium, big monsta!

Thanks for all of the critiques, they are very helpful. This thing just started out as a doodle and just grew afterwards, probably why there is not much detail.

I will improve this pixle art, but won't it be somthing completly different? As in: should I edit this one or just post it as somthing new? 

Cool lines but not so great colors. Try desaturating and hueshifting alittle bit.

Shading looks really off too.
