Often with me i draw from फिल्में sometimes and it helps me think a bit and helps me work through challenges. आप could also give a comic strip a try. Like the person before me कहा take a scene या chapter from a book या your own mind and draw a little comic strip for it.
From my view of your drawings I've got a little constructive criticism for you. आप lack dimensions. That is something आप could work on trying to make drawings with perspective and add shadows. A good exercise to work on it is exploding box effect. At this link आप can see a pretty good example of it.
link Another thing आप could do i learned this from my art student teacher. आप put dots down in a pattern with curves like आप can make a cursive एल या C etc. या something आप designed yourself as many dots as आप want my first one was about 200 something anyways. Your total number has to be a multiple of three. When आप divide your number द्वारा three it should come out without a decimal. Once आप have the number आप go to the dot number that it is and start drawing lines from there each dot should have a dot corresponding to it. आप draw a line from that dot number to number 1 and then आप go to the अगला one and draw it to two and so on. I believe it was called a helix when it was explained. It should look like a cool spiral type thing when its finished
