Yes, any appreciation is better than none. Take me for example. I've taken part in every RooBet art contest, and I've never won a single prize. But the process of creating something which can be called "art" is so pleasant that I participate in another contest, and then in another one. Now I know from my past experience that getting any money prize is highly unlikely for me, so I'm saying to my wife "I hope to earn some merit with it, at least". And I mean it. I value merits a lot, and I feel really happy when getting them. 
I have also learned graphic designing a little but have not participated in roobet art contests but planning on for the upcoming one.Whenever i create something it gives me immense feeling of joy but the more happiness comes whenever someone appreciate it in any format whether merit on forum or other way in personal.There are people who just love to submit its because the excitement is different if you submit your art on the contest compare if you are just a regular spectator. You will also feel excited with others submission since you will also speculate if they can also win and comparisson will happen but anyways for sure other will not think about to win since some other people like you just want to present their arts and want to be appreciated.
