I quote myself to be more clear : "If it's your first try ever at 3D, I put my thumb up."
What I meant in this case is, it's a good job for a first work in 3D. You've shown some serious motivation to be able to complete your project within a month.
About that post to be your first one, I wanted to get you to understand that you've to make your posts more attractive if you want some feedback : a picture of each model would have been a great addition.
Now go back to work, practice 3D as often you can and keep us updated of your progress !
