What Can I do to make the Lightning Stand Out?
 

woah...
nice...

for the lightning, I suggest to create negative space around it by erasing a tiny bit of the hand,
and have the color fade out into said negative space

Wow! It is really impressive! I agree with Nasagi Rei's suggestion, or you can do that and add some white acrylic paint? (That is what I always used to highlight some of my artworks...) Or mix white with golden or any colors to emphasize the coloring and hightlight of lightnings?

Wow!
Thank you guys for your support on my opinions!

I myself am an artist.
Maybe sometime soon I'll post my art!

Unfortunately, I'm too much of a perfectionist to finish anything right now...

WOW!!!!!!!! That is amazing. You are really good. That's the best I've been in a long time.

The white around the lightning would help it stand out, but also it would help it to stand out if you put darker darks on the hand, but make sure to leave bright lights too :O

You might wanna try hints of yellow along it. I dunno if you think that would take away from the balloon, but it's something I may try on like photoshop or something.

She said what I was gonna say. XD
It's a an awesome piece of art work, though! The details are amazing...and the concept is original.
Extremely nice. ;D

first off i just wanna say WOW! ^^
it looks awesome, i love the way you've done the clouds there's so much detail in there, and the balloon the orange really makes it stand out, it looks beautiful.

The only thing i can see wrong with it, is the pointer finger the base of it looks alittle to big (dont hurt me)

i would totally agree with the others, but if you wanted to do for something a little different, maybe try an night time image, make the background pitch black and the lighting white with flecks of orange in it to match the balloon, this would also make the balloon stand out even more.

All in all it's a great piece of work.
