Show me your little boy's bedroom please

We have a sea mural on 2 walls but still deciding what colour to do the other 2!

Callum and Aidan share a room atm so we went for a basic colour with no gimmicks, deep red on one wall, magnolia on rest with a red blind and carpet. Worked out well though as Aidan in Liverpool FC mad and Callum's now got an interest in Fireman Sam so they are both happy.

William has a toy story room ATM. I'd like to do a jungle room or generic space room iykwim.
It's hard tho cause we're renting and like Tory said you really can't do a lot. Although I have found the magic stickers are great as they don't ruin the paint.

Max has a very plain design to his room with plain painted walls but he does have this bed. In the black and green star. It's all about the bed

Kieran is older but he has a funky blokes wall paper on one wall (black and grey) the other walls are quite a bright blue and on one of them he has the ikea world map wall hanging which is pretty huge

We did James' bedroom in December after we moved in. (the dreadful ManU paper, carpet, curtains HAD to go!)

He's animal mad - so he's got a jungle & dinosaur bedroom. With a hand painted mural of each of the 2 main walls.

Ocean has a deep aqua on the bottom half and a lighter aqua on the top. This is divided by a sparkly purple, thick wavy line, which the chimney breast is painted in as well. He has purple curtains to match and then a deep blue, very soft, carpet. One one wall, under the purple wavy line, he has colour-in monster wallpaper.

We need pictures..............

Was it worth the price? Is it really good quality, etc? Just that we've got a huge map of the world and it was £5. I wouldn't mind replacing it as it's getting tatty, but would want to know that it's worth £100!
