I like the mood, however, you should add a shadow and try to remove the white outlines from the spider, other than that there's not much else to do, although it would be more eerie if the spider was darker and hangin from the trees. Just my opinion, good luck.

I'm with pontiSS - I feel the spider on the cabin is a bit inanimate - if you can 'bring it to life' you'll have a great chop!

Scary... Good job!

nice job

I love the mood of this image but I'm missing the final details like shadows. The spiders have a bit of a cut&paste feeling, this can be solved by adding shadows, both on the spiders and the surroundings. Hope you have time for some adjustments. I think, when done well, it's really worth the effort and will benefit the image.

Add some shadow author and work will be perfect....

sscaaary... good job

wow great work

Spooky Halloween mood!
