Want to be featured on ISO? Every Monday, we’ll announce a new theme. You’ll have until next Sunday to submit your photo as an entry. You may already have an existing photo that fits the theme, or you can take this as a challenge to shoot and upload a brand new photo.

Last week, we asked you to share your awe-inspiring images of Motherhood. And the timing was perfect—our 500px CTO Renat Gataullin just had a baby, and became a parent yesterday!

We have received 160 entries that celebrate motherhood. Thanks to everyone who submitted their gorgeous photos. One photo was chosen by our editors to win a special Mother’s Day prize package:

“A Mother’s Love” by Angie Marie Photography

Congrats, Angie Marie, you have won these prizes:
1. Awesome account for ONE year
2. Official 500px T-Shirt
3. Signed card by our CTO Renat Gataullin

Because we think every day should be Mother’s Day, here are 18 more of our favorite photos from the Motherhood gallery. Scroll down for the runner-ups:

New theme for next week: IMPACT

1. Select a photo that fits this theme. Upload the image, or pick a photo you’ve already uploaded.
2. Add the tag #500pxImpact
3. You’re done! Track all entries here.

Crashing waves. High-speed explosions. Glass shattering. Splashes of puddles. Lightning strikes. There’s nothing like capturing a moment of impact to make a photo powerful. This theme is open to your own interpretation, so grab your gear, start shooting, and tagging now! Deadline is May 18th at 11:59PM PT. Good luck, everyone!
