Surprising Boom

Hey everyone
This is a picture I actually wanted to draw for quite some time^^ It´s finally done and I worked pretty fast compared to other drawings so far xD Most of you might know, that SpitDash is my absolute favourite shipping and I enjoy drawing them both together, trying to show their romance and love towards each other The title "Surprising Boom" shows the spontaneous kiss and emotional explosion of them, similar to a sonic Rainboom, but more romantic  
To be honest, I struggled a lot with this drawing, because of many different things. At first: Drawing RD´s mane is more than hard, I swear, I had to re-do the different colours around 9 times, it was exhausting -,- After that, I was pretty disappointed about her shading and how the light effects etc. turned out. The same thing happened when I drew Spitfire. I don´t know why, but I had problems with shading these ponies, so that could be a reason why it doesn´t look as good as I hoped it would. It´s your decision if the shading was better in other drawings or not, I personally can say, that I could have done it better, but I´m kinda glad it´s done.
Nevertheless, I actually like the result and, that´s what I love about this drawing, the eyes. The eyes look sweet in my opinion.
But what do you think? I hope you like it and I´m looking forward to your feedback
