Good, not great

The light on the mushroom makes it look like shiney plastic- great 3D effect, but not realistic for any mushroom I know. Also, the gills underneath come together at a point just in front of the stipe (stalk) instead of around it.

I don't have a problem with the green background except that it is only behind it- the mushrooms need to be growing in and amongst something- if you put a few blades of grass in front and around it, the problems your critics refer to would IMO dissappear.

Try studying some real fungi and improving this one- it would be a good excercise- everyone here draws people and faces- be different!

HmmM

Good....But it is strange to involve plain mushrooms. Most drawings you see colorful ones such as SHROOMS but i don't think this a good enviroment for these type of mushrooms. But i like the idea, and effort that you put into it.

MUSHROOM MUSHROOM

Not only are the mushrooms at a strange angle, but seem absurd compared to the conceived size of the grass in the background. I'll agree, if you replaced the grass behind the fungi with a tree's outstretching root, it would look great. Right now, it looks awkward.

cool but..

the moahroom is amasingly detailed, yet, the ange you used to perspetivate the mooshrooms is diferent than the one you used for the grass...

IMO the would have looked just great if you would have done them on the root of a tree.

Great work
