Let's start with the great:
I like:
+The detail put into it - for example the walls you can jump through, the stall/stable doors that open, the fountain, etc.
+The plants really add a depth to the scenery
+The furniture is unique
+Good starting weapons
+Fun jumps
+The layout is simple but effective
+The windows are very original and consistent
+You did a great job picking textures for which we currently have hi-resolution textures for (between the different packs) and it helps make the map look really good.
Stuff that I'd like to see fixed in beta 3:
-In the bases there is a clip or nodraw brush that has the shadow from the plants (I can give you a screenshot if you'd like)
-Some areas within the castle have little to no lighting, I think it'd be nice to have at least a little lighting here. I just realized this was intended to be sort of a 'secret' bonus area, or I assume it is because it has an autococker, so the lighting is fine there.
-The boxes (with the X texture) and some of the ramps seem very out of place. You're very creative, maybe find something else they could be replaced with? I could make you almost any custom texture you need so if you have an idea, let me know. (I.e. a crate that says 'feed' or 'cannon balls' on the side)
-The rocks in the middle are identical (rotated?), maybe make one different?
-The name doesn't seem to fit the map, maybe I'm missing something? Wouldn't be the first
All in all, this is my favorite 'first map' ever. You went above and beyond, paid amazing attention to detail, and the end result has so far been spectacular. But for the love of Jehovah, I get 120 FPS in SLI in the mid of your map! Maybe find a way to drastically reduce r_speeds? You did a final compile, correct?
Cheers and good luck on this great map,
