Okay, I would give your trainer sprites, especially the newer ones, 11/10's
BUT the outlining and shading is just a bit off, and even a bad on a few... i'll leave the old ones be, since you're not using them, instead, i'll go with the new ones...
These lighter pixels don't look right here, especially if the light is coming from the top left... i'd say darken them...
These should be lighter, since the light is coming from the top left and would be shining directly on them...
Is that differently colored pixel part of the design? does he have a bleached band across that strand hair? If so, i guess i get it, if not... well, it doesn't make sense then...
All the pixels being pointed need to be lightened, and skin toned... use a darker tone of the prexisting skin color to replace these... the skin color is a nice set...
His arm looks very jagged at this point... it needs to be smoothed out a bit, he's got a kink ^_^
Random gray pixel...
More random gray pixel...
(HIS) right leg is skinnier than his left leg... (looking at him, that would be our left leg...) ... it's skinnier by two pixels, and really narrows out at the top. it is very awkward looking... the other leg looks great in contrast...
Overall, this sprite needs work... the anatomy is a bit off in some spots, like the arm and the leg, but also, HIS right arm also seems to be a bit too long... if they were both down at his side, it would be longer...
The outlining is what is really killing this sprite though. You cannot just make it all black, it leaves an awkward contrast to the backgrounds, and detracts from the shading and the look of the sprite... the hair also needs some outlining where it meets the face on the right side there... it's so flat looking right now...
The shading is good, but could be better: i wouldn't change the pants since they look nice with that shading variation, but the shirt is
too wavy looking. The face and neck also have good shading... nothing to crit there... the hair though, especially on the left side, it needs to be lighter, since the light is directly hitting it... (the part where all the dark green arrows are pointing...)
Both of his arms seem mishaded as well... HIS left arm seems under shaded, it should be darker towards the right of the frame... and the other arm needs to be darker around the bands, but not all along the outline... it would still be light there since that's where the light is shining... just touch that up probably...
All in all, i give this sprite a 7/10. It is VERY GOOD, but could still use improvement.
I'll leave you with this one for now... and we can go from here...
Take my crit sparingly, don't get discouraged, and most importanly...
Keep Spriting!
OMG, i almost forgot...
he has no nose!
