A good first profile you have there m8, looks fresh and clean and you have a good subject.
There are some anomalies which stand out to me, such as the engine has a darker shadow than the rest of the aircraft. You have used lines to create the under wing radiator shape rather than tone and for me, I like to see a little bit more contrast overall.
I noticed that you have a backward perspective on the under wing markings, which on profiles you cant really show or you’d have to show it on the rest of the profile (defeating the object of making a profile in the first place). “But that’s just my opinion, overall, I think it’s a great start”.
