Greetings Madi! Nice to meet you. I too am a new user to Tapastic and posting a webcomic of my own 
I enjoyed what you have posted so far of your comic Deserted Flowers, and have subscribed! (I figure that alone is probably more meaningful than throwing too many compliments around) The story is off to a dramatic start, and I'm intrigued about what is to come. It will be interesting to see things as the narrative has chance to slow down, and characters develop together.
I read it on my iphone, by the way - so a relatively small screen compared to a PC. The colours popped nicely and everything was perfectly distinguishable. So good job!! Looking forward to more content.
