@Calista & Shahar, thank you both for you help on 48.

Regarding 49, I really think the answer is incorrect, but thanks to Calista I could pass it.

For 51, the answer is very simple, and is located in the picture
some of the letters there can give you a hint

51 might be simple but I don't get it. I did understand it wasn't a rebus. Are the colors important?
Edit: Nevermind, I suddenly saw it.

Hmm 55 looks tough. I have to say I stumped! No idea how to start or what I have to think of it. I better take a break before I am going to crack my brain onto this one.
edit: Alright 55 was much more simpler than I thought.

And stumped on 58. I think I even don't understand what's precisely asked from me.
edit: I indeed understood it all wrong. Thank you for your clarifying explanation, Calista.

Stuck on 61. I know the answer, but once again the wording is giving me difficulties.
Edit: Nevermind, I made a seriously stupid mistake.

And finished!!
Thanks to everyone who helped me along the way! Too many to name.

@MLBM, very nice riddle. I really liked it. Although some were damn tricky.
