Welcome Ollie! Thank you for your service in our armed services, and good luck with wrapping up your degree and the job hunt.
Your modeling experience sounds familiar. You are most definately in the right place to improve your modeling and learn new skills, and you've now got dozens of topshelf "consultants" to help you along.

Seriously though, use this site and forum, and don't be afraid to ask about anything. Usually, we all learn something when someone asks a question here.
I was like you about a year ago. I now have five 1/32 kits completely successfully, and two more on the bench right now. Don't even ask about the stash.

My results are largely becasuse of the learning, inspiration and help I receve from this site and forum members. I suggest that you read the basic tutorials by Des and others such as workbench setup, rigging, preshading, etc, along with build logs for the kits you are doing. Do what Des suggests---it works! Don't be put off by the inevitable setbacks of modeling. We all experience them. You'll just learn to regroup and overcome.

I think you'll also enjoy the cameraderie and personalities on this forum. Not a day goes by when I don't get a smile or a chuckle from someone's post here. But mostly, I learn and am inspired. You will be too, and we'll see some fine builds from you before too long! Good luck!
Regards,
Bob
