It overall looks pretty good! Just a few things to keep in mind:
The black bars look a little obvious so you might want to try and find a way to blend them in a little better.
You could try adding some CCs to the pictures as it doesn't look quite right with them being many different colors.
Also you could have just done all caps for the text because the lower case letters do not help the design very much.
All that said, does not make your design bad, it is a good idea! Keep practicing!
Oh well this looks really good and I would say maybe use something else other than black bars I mean its good but maybe something else to blend in much better and yes you can cap the letters as Caleb said but I guess its good and u can also use CC just to give a variation
the pictures and the bars sticks out really much try having a little fade on the blackbars and make all the colors similiar or just make them black and white which also works great, overall good work!
