Try again fail better

hey man, nice amount of work. If you take a step back at your painting, you'll see that they're almost all not lighter than the reference, and that's what makes your painting a bit flat ! you must push the contrast harder than the reference, try to exaggerate a bit what you see, concerning edges( harder and softer), values (darker and lighter) , colors (warmer or colder ) . This way, you'll think a lot more ! and be carreful on your proportions !!!!
