Canvas HTML





    For my Canvas project I recreated a previous illustration I drew, but in a different fashion. I wanted to recreate this illustration because I thought it would be interesting having to create it using a collage of shapes rather than free hand with more curved lines. What it stands for is always in the back of my mind, in addition details such as the sun, which I did in a more cubic, Mayan manor. It took me about 12 hours to understand and write the code. At first, understanding how to fill the the shapes and how they interact with each other was a learning curve. However, the picture became more vivid after I got into the flow. I think the original sketch on graph paper allowed me to plot the lines and shapes easier so I could spend more time on thinking of how to build the picture in general.

    My original illustration had more flow, and exhibited more curves. Since the great deal of the project was based around shapes, I decide not to focus on curves, as much as building the picture with shapes. I used curves to illustrate simple things like the birds. One shape I used a lot was the circle, as it applied in many areas of building the image and looked good when layered. I made sure to include all of the colors from the original illustrate because of their significance to the meaning. I did not want any gradients because I thought the colors in contrast, popped more.

    Your canvas project is very nicely done and incorporates a lot of varied designs that work well together! I really like the 3D effect you gave the sun on the corners of your canvas, it helps it stand out from the rest of the visual elements in your image. I also like how the semi-circles on the bottom are colored in with different shades of green. I would suggest adding more detail to the birds in your image so that they are more distinguishable. Overall great work!

My Intentions For Fall Semester

Image
    Good Evening, my name is Isaiah Stephens. Im from Baltimore, Maryland and have two younger brothers who motivate me to get up every morning.  I am very optimistic and genuinely excited to be in Digital Media. I had a Digital Media class in high school, and that class was easily one of my favorites because of the creativity involved. In addition, I think Ms. Roundtree is a good professor judging by the first day of class and her online resume. I would love to get to know you, Ms. Roundtree, on a personal level to understand your struggles and successes having held certain positions involving creation and PR for businesses, as well as being of a different nationality. Many of the jobs you've held, such as creative directing for an entity, is exactly what I plan to do for a living and having a professor with personal experience,  I think could really help. Also, I have a pretty good general knowledge of all of the Adobe programs because I enjoy creating and editing in my free time
