Congratulation, Texence. Its an eye-catching pic with stunning colour and nice composition.
The discussion here is about the PS work you have added to this pic. In my opinion, PS is becoming a standard in digital photo processing, and I use PS to improve my picture quality in terms of level, contrast, colour, saturation, framing, etc.
But I would not recommend to key in any foreign object into the original work (only my personal base line, nothing to do with "right" or "wrong"). If you really need to do it, state it clearly when you submit it. Let others critique your work not only on your photo technique, but also your PS creativity. In some international photo websites, PS masters earn the applaus of others. But they will normally tell others what they have done in PS.
Anyway, this is a good piece of work, and I have no reservation in giving you a vote!! Happy shooting!!
