My first alteration - table

[Untouchable]

Try to make the lines 2 pixels accross and 1 pixel high all the way along.
I suggest you read some tutorials but I don't have any.
The drawer in the table (at least I think it is the drawer) should not be made using a spray can thing.
The bowl requires shading.
The mat has weird lines creeping up in but the table need the most work.
All the alts are very big and a Habbo would not be able to use them.

If you read some tutorials you will get the hang of it.

Umm..
Not fantastic, yet not terrible..
This needs a lot of work.. take more care when doing straight lines, and try making each line the same length.
I suggest taking some of the advice already given in this thread.
Everybody has to start somewhere, and this is your first alt! So yay.
Maybe read some tutorials around the forum?
