A request

Hello.

I am new with MuseScore and slowly learning how to make sheets in this program, but it is going veery slow :s My friend is playing piano and I'm trying to help her with it looking for some nice musics for her ^^ I have found a nice melody that she likes very much and trying to add it to MuseScore but its going hard and some sounds i dont know how to make..
I wanted to ask if any person here could help me with this one? I have scans of the sheets, now trying to put them to "digital form" with MuseScore. If anyone could help me with it i would be very grateful.

Thanks in advance for any replies, Karol.
