Like, the simple lines. And interesting touch that the brain is "grounded". FONT too common, or toylike. Plus too small. Color of font, see other entry, don't like red/dark orange. The Brain however becomes too hard to see, although it is a nice idea that its a flower/leaf, but it looks too much like it, and too little like a brain. It could potentially be good to see what your style would do if you made a human face outline instead.
Hi Dije, to be more precise in our feedback, can you try to use the outline like we write in the brief we would like to see a gorgeous female head, and could even be a real human head with hair an everything, pls see the picture we have attached for inspiration. Do not like the font so much, and the + becoming to thick. Hope this helps.
