Hi Riptide!
Welcome to the site! First let me say, congrats on seeking critique/comments, it takes some bravery to put yourself out there after all!
Just wanted to give you a couple quick tips to make sure you can get the feedback you’re after.
Since you’re uploading to your profile, via your sketchbook, I take it that your have either a full or doodler membership? If so when you upload images, make sure to check the box “Request Critique”, that way when folks go critiquing, your work will automatically be added to the queue and it will be seen! (I noticed the images in your sketchbook say “is not requesting critique” which is the default if you don’t check the critique box)
The other way to seek critique is to use the Critique forum and upload images into a post asking for feedback. I did a copy-paste below of the FAQ about uploading images to the forum in case you aren’t sure:
How do I post images on the forums?
If you have a full or doodler membership, the easiest way is to upload your drawing to your sketchbook. The shortcode that you need to post the image on the forums or in comments around the site will be shown on the drawing's page
If you want to post an image that is hosted elsewhere, such as on an image upload service like Imgur, Photobucket, Imageshack, tinypic, Imagesafe, or another, then you will need the direct link to the image. Only links ending in .png, .jpg or .gif will work.
That means that a link like this won't work to embed an image: https://imgur.com/gallery/q0O8G
But this one would work: https://i.imgur.com/beASDB9.jpg
Note the .jpg at the end of the link! This means it is a link to an image, rather than to an entire webpage.
Once you have a url for your external image, use the img shortcode to embed the image on our forums
Remember, if you aren't linking to an image from your Line of Action sketchbook, make sure that the link ends in a valid image filename, like .png, .gif or .jpg
Since you are relatively new to the site, why not do a Critique forum post with the images you would like to get critiqued? You’ll be able to have a conversation about it with lots of folks and it gets frequented a bit more than the auto-critique system.
Anyway, hope that’s of some help and we’ll see you around the forums :)
