KotH Downhill

A fairly simple koth map I roughed out in a few days, koth_downhill is my second (hopefully better) attempt at mapping. The basic layout consists of a general downward slope towards the center CP, hence the name, with the control point being the dominant feature and largest structure (at least in this alpha). The premise is that RED and BLU, simultaneously discovering secret technology in an abandoned mountain warehouse, know there's only one way to decide the owner of the shack: war!

Also, please ignore the lack of a 3D skybox and of detail in general
My main concerns right now with the map are:
*It's too small
*Needs a skybox
*Retexturing & more detail
*More gameplay elemnts (it's rather bland at the moment in my opinion)

Any suggestions or constructive criticism is welcome.

Yeah,it's really small atm, but i'm trying to expand it. Right now the dimensions are around 3000x300hu, and i'll try and end up with around 8000x4000 or somewhere around there. As for the skybox, i'm still working on it.

Thanks for the tips! I kinda recognized the sightlines before, which is why there are all the random wooden boards in the ground, but yeah,I guess it's not enough. Any ideas on how I can cut down the sightlines besides prop/brush spam?
