I always find the way GCSE and to a certain degree A level art courses are taught are fairly limiting and not representative of how art and design 'works' in the real world, particularly the examination process which seems to be based on how other subjects are judged, which is often against the clock. Sure, graphic designers need to be adept at knocking out work to a deadline, but a fine artist often needs inspiration. Sometimes it's there sometimes it isn't.I did an Art GCSE, but found it very limiting, largely due to the above points. I could so easily have given up.After that I did a full time (8 hours a day 5 days a week) Design course for a year and then a further two years studying General Art & Design. These courses were fantastic and because of their full time nature, the work could be judged much more fairly.The mantra at art college was to produce as much work as possible and not spend too long on any one piece. My art tutor was dead against the idea of a 'masterpiece' and wanted students to instead be adept at as many mediums and materials as possible. He was a very good teacher.Have to say again, considering you've only studied to GCSE level, that's a very strong piece of work. Some people can never get perspective right, like you say, particularly with aircraft illustrations.
