I love the concept behind your design but think for our purpose the brain would need to be simplified. The font is very fun but needs to be bolder for distant viewing. Also love the idea of the paintbrush coloring the brain but missed that until just now, originally thought is was just a line. That area reads a bit busy with the ball/rays/brush/drips/font all together. Could the brain be simplified, maybe a more cartoon like side view without the ball/rays. Maybe bring a side view brain down and at an angle in the space under the b by toys and the brush out a bit so that the drips can land on it rather than in it?
Again, love where you are going with this! Nice work!
Thank you for all your time and efforts :)
