Youre enthusiasm is there, but to be honest you dont understand how our mod works i think.
You dont just "offer" us a map you are working on. You apply formally with some details about you and some media shots of your work straight up, as if a commitment to the project if you want your map to be in our game - and continue to help the mod.
No mapper from here i can conceivably see taking over your work if thats what you are suggesting. If you wish to show us your skills by way of screenshots and formally apply with the "formal" method we would be more inclined to take you serious. Show us other mapping youve done in hammer too! it will show us your brush work limits and potential.
Again i like your perspective on the fact GE:S exists and you have a map you are excited about (not tryin to be harsh), but you act as though we privelidged to recieve your work and that it is a small-time project. We've won mod awards, we expect certain levels of professionalism in favour of your post.
