Thankyou for the feedback, it is always good to get other people's opinions as a fresh pair of eyes always helpsI like these.....especially the Stitch one....solid colour packing...I have always found it hard to pack the pastel type colours...light blue and pinks...you've done well with this one.
I'm not liking the butterfly skull as much, some of the lines are shaky and some double passes and I'm thinking that the black isn't packed as solid as it could be.
I love the concept of the mad rabbit thingy but as with the butterfly one, some lining is inconsistant and I saw a couple of lines that didn't join up .....I'm sure your mentor would have told you all of this (well, I'm hoping he has) It also looks like it may have been rushed a little, as in you needed to get it done within a time frame and the stipple shading in the rabbit needs to graduate a bit...it's too consistant in darkness ....needs to go from dark dots to light...whip that needle out instead of keeping it the same depth in the skin.
Hope you don't mind this critique.
