You are making some great progress Harrison. It shows in what you are doing on your other build. I know it can be difficult to absorb all the tips and suggestions people are giving you. Its up to you to pick and choose what works best for you. I think one of the most important thing is taking your time. Don't let the deadline of this GB force to to rush and make mistakes. There are people out there who will tell you how a model has taken them over a year to complete. If that is what it takes to get the results you want then so be it.
You may not realize it but you are definitely making progress when it comes to your skills.
