I think you should probably wait until your maps are a little more complete before releasing them as beta. "Beta" usually means "complete but needs testing and minor tweaks". A lot of your maps seem to be still in the WIP (work in progress) stage, which I think is hurting your reputation. You should spend the time completing and fixing things you know need work, then when the map is done from your point of view, release it as a beta for community feedback.
Some things to focus on:
- Make your paths clear, fun, and balanced. Time the different paths and make adjustments so it takes roughly the same amount of time to take each path.
- Align textures as you go. You have a bunch of wood detail. Making a wood brush, aligning it, then copy/pasting it is a lot faster than making a whole bunch of them, then going back and aligning them later. Also, in the case of the block textures, a lot of times it's easier to build the brush so it aligns with the texture rather than the other way around. A lot of the brushes are .5 or 1.5 blocks thick. If you make them 1 block thick, they'll be aligned for the most part (you may need to rotate or shift some of the block textures, or shift the brushes so they align).
- Watch your r_speeds. Lots of detail + open areas + reflective water = high r_speeds and low framerates for some players. Try to keep your details to areas where not a lot of stuff is going on and you can afford the extra polygons.
