Yes, i do make maps for Source too, and due to my disappointment to Gm_Toyroom, the first ever attempt at Andy's room from Toy Story 1 in Garry's mod, i decided to work on my own, albeit higher detail and more things to play with.
The video of Gm-Toyroom can be found here

Old things begin here.
So, i began working on my own version, here's what i've been working on for the past day [Yes, i'm using the Tf2 SDK]

So, i've finished constructing Andy's bed, and two of his drawers, but without textures, they'll be coming later.
I'll be trying to recreate everthing that usually appears in Andy's room for this, and for t he people who are wondering, you'll be the same size as a Buzz lightyear in the map, making it a possible great place for ragdolls in the future.
And many parts of the map will be physical, so you can do things like tip over andy's desk chair, move his plastic ball.etc.
More updates will be posted here.
Anyway, comments and criticism will be great, and possibly suggestions?
