Well first of all welcome to tibweb and we hope you like hanging around here and making maps for TS.

As far as the map goes I must say it looks pretty good and I assume that this is definitely not the first time you have tried to make a map. From what I can see in the pics it appears that you have a good understanding of the basics of mapping such as cliff placement and the use of marble madness as I can not see any cliff errors or any thing like that in the pics. (provided the pics have been reduced in size due to tibweb's thing and also the pics are just a wee bit dark In my opinion.)
My only slight problem that I can see of as of right now in the pics is that your green lighting around the green tiberium seems a bit blocky as it furthers away from the tiberium fields. This is a lot more noticeable on snow maps and is kinda hard to get rid of. I think the main thing that is causing it is how far your invisible green light posts visibility is and also how the generic setting of Level for the map is set on. I suggest making the Level setting in the map lighting almost all 0 across because it is a problem on most snow maps.
Other than that I would just brighten up the map just a little bit overall and I think it would be good to go.

I hope to see this released sometime soon.
