I'm gonna be honest, this is the best of the three. The digitally adjusted has the better effects, and the day photo is the most washed out, but from a stylistic standpoint this is the greater image. The way the green colors pop on this version combined with the contrast of the red plants really makes the extra blue and yellow layers unnecessary on the digital version, and ends up making the end result more in-line with your style.
I also really like the yellow streaks on the plants being more grainy in this version as it adds more texture to them, but the final choice on which stays is up to you. Keep up the good work! I'm really liking this new style that you are trying.
