Sorry, but it looks absolutely awful. I know that you say this is very low alpha, but it looks like a grand total of maybe 20 minutes of work. The concept is also kinda poor because of a few things;
World of Warcraft is nice (for me and for my sister as well) because of how natural and nice it looks and flows. Blockland simply isn't a medium where you can have the perfectly smooth terrain and playermodels and animations.
The combat is relatively interesting. This cannot be the same in Blockland; it's built into the client.
There is a lot of depth and fine detail in the game and I sincerely doubt that you can replicate it.
