Nice pixelart.
Could work a bit more on shadows. Just a tiny tinie bit but that'll come with experience.
Just the missing space in "OH NO!IF..." is a bit awkward.

After all - great job d00d!
4.5/5 Stars

:D You cant and NEVER will, EVER. Especially now.

ITS SO FREAKING CUTE ITS ALMOST MAKING ME WANNA CRY!
This puss is totally ready for ADVENTURE.
Is that a mask on top of his head? Was looking kind of "helmety" for a sec but I see the eyeholes. WHAT IS HE POINTING AT?! I bet its freaking awesome. :D

Dont forget about your spacing, you were doing so well.
Mainly looking at the type ("NO!IF") and the kittys body (his belly is off center and the strap from bag is kind of bulging in the middle)

But seriously I love you for this... Its...just...adorable :D. I find that with every piece of work you come out with, its honestly getting better and better. Keep up the great work hun.
