It seems the word "art" may be inappropriate, I prefer "fantasy", "fun", I do not pretend to reach "objective beauty".
I do like transforming a little an aircraft into something impossible, or obviously wrong (to be rejected, not built and flown at all).
The argument "if I draw an airplane, I accept to be criticized if this is a bad airplane for customers" is completely wrong: I am not at all a professional engineer taking money from customers, coming after pleasant advertisement, not at all. I am a lab-tech in microbiology, just playing (in the evening) in inventing crazy shapes inspired by airplanes. If Walt Disney draws a mouse that speaks, will you criticize him because mouses are real animal and real mouses don't speak? please shut up and let the dreamers dream. if you don't like this, feel free to follow your own way, but don't come here to criticize. My son is 7 years old and I learn to him "be gentle and the others may be gentle with you, if you are bad with the others they will be angry and so they will be bad with you, this is a bad calculation for you". You should complain about your father, having not learned you life properly, killermodeler.
