Hey there! It's always good to go back to the fundamentals from time to time! :D There's always something new to learn—or relearn—and improve. If you have the chance, I'd recommend taking the drawing roadmaps here on ArtWod. I'm pretty sure they'll help you develop your skills even further, especially when it comes to shape manipulation. At the end of the day, drawing airplanes, or almost any man-made object, is largely about understanding and manipulating simple forms. With that in mind, I'd recommend focusing on exercises that primarily develop your shape manipulation and perspective skills. One exercise I really enjoy is combining two simple forms, then creating two new variations from those combinations, and finally combining those results again to generate even more interesting shapes. It's a fun exercise, and it's great for training your design thinking. Keep it up! :) | Artwod Feedback
