Things to fix
Little Crack.. misaligned brush?
I think the sloped brush should line up with the front of the house
Misaligned
Misaligned
The supports seem a little skinny..
Grass Texture? might be part of the misaligned wall from above?
Whats with the blocks of wood?
Also the base to mid to base speed jump seems a little easy, and is much quicker than everything else, although im sure it will get the feces lined out of it.
And you can hit your head on the ceiling when doing the speed jump.
Also what is the point of the smoke in the tunnel? I dont get where its coming from..
Also the lighting is boring, it barely seems like there is any.. try to make it more.. dramatic
Other than that, good work!
EDIT: i found another misaligned brush. Going from the base to the mid (speed way) you will see along the wall a misaligned brush on the left side
Also i realized what all the smoke is from, a fire, which is not visible since there is too much smoke..
