Yeah :/
Doesn't much look like grass, more like tree tops in a forest.
Nice though.

Any tips on how to upgrade it?

Don't make them bush like. Perhaps make them look like this:

Except make them bend and, make more leafs. :v

Here's another tree I have try to make.

Nice interesting tree....
I'm not liking the flip of the trunk though.

Btw don't tell me nice to make me feel happy

Just tell me what to fix on it if it's ok or not.

Because im posting this on 2 forums this one and a pixel art forum to gain more tips on what to fix and so.

Okay :/
Well I'll be waiting for the newest tree, or what ever you bring next

Non coloured trunk.



Seeing if I schould change anything else to the trunk.

'Don't worry with the white colour'

Perhaps you shouldn't make a rounded top. Maybe jagged like it got hit by lightning.

Nvm im not posting my pixel works here anymore :P

Will just post it on the pixel forum and recieve advice there.

So far I made another new trunk.
