Safe

As you know, i'm no good at alts, so here is my safe..

You have the right idea..it's not that good though, try reading a tuatorial.

Its not isometric, it has not very good detail, no shadeing.. 0/10

not noly that but it looks like you didnt even try with the combonation
come on, i know you can do better

thats really messy, you have a good idea to work on, now use that idea, try making all the symetrical lines parrallell 1st.

Ugly. 1/10

Well i can see where your going and its also a very good idea. try adding some shading to it. ;)
