It popped into my mind this likeable caveman and I had to sit down to draw.

Hand sketched and outlined in Illustrator (I think from tomorrow I will have a wacom tablet to do these things, hopefully will be easier with that!)

If you need me to make any changes, let me know and I do it gladly. I will upload the original 'AI' file and a 'PSD' (exported from Illustrator) as requested in the collaboration.

Hope it will be useful! :)
